Abstract: Preceramic compositions which have particular utility in providing protective ceramic coatings having low moisture sensitivity on carbon/carbon composites, graphite, carbon fibers, and other normally oxidizable materials are prepared by dispersing 0.1-1.0 part by weight of a Group IIA metal salt with an organoboro­silazane polymer solution obtained by reacting 0.25-20 parts by weight of a trialkoxy-, triaryloxy-, or tri(aryl­alkoxy)boroxine with one part by weight of a polysilazane in an organic solvent and, if desired, heating the disper­sion to convert it to a solution. If desired, the composi­tion thus obtained can be modified by dispersing 0-3 parts by weight of aluminum-silicon eutectic, 0-4 parts by weight of silicon carbide, 1.5-5 parts by weight of sili­con boride, and 0.4-5 parts by weight of silicon metal therein.

Abstract: A method and apparatus is disclosed for determining an objective measure of performance of an extended finite state machine. Many modern complex systems, for example, computer communications protocols and computer or machine user interfaces, can be represented as extended finite state machines. A formal description of the extended finite state machine is employed to obtain a canonical form description. The canonical form description, combined with a service description, is used to generate a list of canonical state transitions transited by the extended finite state machine to perform the service. From this list, an objective measurement of performance, e.g., the time required to perform a particular service, is obtained. This objective measurement may then be used as desired, for example, to select an optimum extended finite state machine from a plurality of extended finite state machines.

Abstract: A method and apparatus for operating a video game, controlling the cursor position on a computer display, and controlling the operation of equipment and devices using electro-oculogram and electro-myogram signals resulting from eye movement and muscle contractions in the human body. Operator (10) wears sensor assembly (12) which is connected to control processor (18). Movement of the eyes produces electro-oculogram signals which control processor (18) detects and converts into separate control signals representing upward movement, downward movement, movement to the left and movement to the right. Muscle contractions produce electro-myogram signals which control processor (18) detects and converts into control signals. The control signals are interfaced with equipment (22) which is a computer or video game having a display (24), or other apparatus to be controlled. The electro-oculogram control signals are used to control cursor position on a video game or a computer, while the electro-myogram signals are used to simulate the operation of a switch or "fire control" button. The functions of a "joystick", "mouse", "track ball" and the like are thereby replicated by the method and apparatus disclosed herein.

Abstract: According to the invention, a drive system designed with extended travel for bass loudspeakers (10) is specified which prevents the voice coil (21) from impinging on the magnet bottom pot and the voice coil (21) from coming to rest on the top pole plate (12) even if the mounting elements are designed to be very soft. For this purpose, a further coil arrangement (22), to which the amplifier power is also applied, is arranged on the voice coil former (19). Since the current is designed to flow in the opposite direction in coil (21) and coil arrangement (22), the voice coil former (19) is actively decelerated as soon as one of the two winding areas (23; 24) plunges into the air gap (25). <IMAGE>

Abstract: The present invention provides an EPROM memory cell structure that is utilizable in high speed UV-erasable or flash EPROM contactless arrays and that uses source side injection for programming. The EPROM cell structure comprises spaced-apart source and drain regions (12,14) that define a channel region in a substrate. A first layer of insulating material overlies the channel region. A floating gate (22) is formed on the first insulating layer and overlies a first portion (16) of the channel region that extends from the drain region to a point in the channel region intermediate the source and drain regions thereby defining a second portion of the channel region that extends from the intermediate point to the source region and over which the floating gate does not extend. The floating gate also includes a coupling portion that extends over the field oxide that defines the active area of the EPROM cell. is A second layer of insulating material is formed over the floating gate, including the coupling portion of the floating gate. A polysilicon control gate (32) overlies the floating gate but is separated therefrom by the second insulating layer. The control gate includes an access portion that overlies the second portion of the channel region but is separated therefrom by the first layer of insulating material. A polysilicon coupling line (34) overlies the coupling portion of the floating gate but is separated therefrom by the second insulating layer. This cell structure is utilized in a contactless array that relies on shared source lines, resulting in very small cell size and relatively simple decoding.
